In Earth's distant future, geomagnetic abnormalities make every day a struggle to survive. The human race faces its greatest threat -- not from aliens, meteors or global warming, but ordinary, every day appliances! With even the most basic of machines going haywire, one man holds the hope of Earth in his hands: karate student Shota, who can beat any appliance into submission with his Repair Blow! Shota is joined in his adventures by the sweet and spicy Momoko, and the street-smart con man Kanji, who each have their own reasons for sticking with the diligent karate student. Whether it's to chase true love, or make an easy dollar, these two will stay by Shota's side through thick, thin and marauding household machines!

I own this one in Japanese. I found it while picking up the rest of Those Who Hunt Elves at Book Off (since the English version of that manga was cancelled! Talk about customer loyalty!). It's an interestingly absurd idea about fixing things through hitting them; exactly the type of bizarre storyline I'd expect from this mangaka. But while the idea is interesting the story is too short and the characters aren't developed as quickly as the short story needs. Still its entertaining if you enjoy gag comedy mangas.
